The Green Caterpillar, which is also known as 1575 virus, was first
isolated in 1991.

The Green Caterpillar will infect both COM and EXE files. It probably
originates from Taiwan. It will infect programs whenever a DOS DIR or COPY
command is executed.

This virus has many known variants. Some of them will have a green
caterpillar appear on the system display and eat all the characters.
This will happen after two months from the first infection.
